What is HVAC equipment used for?

HVAC stands for heating, ventilation and air-conditioning. It is a type of system that provides heating and cooling bor both residential and commercial buildings. HVAC systems used in homes, stores, factory and even in submarines where they help people to be comfortable in their environment. 

The HVAC system is now becoming popular in new constructions. It uses fresh air from outdoors and processes it to provide a high quality of indoor air. The process involves removing of dust, heat, moisture, bacteria and other gasses to provide good quality of air indoor. The primary purpose of the HVAC system is to make occupants feel satisfied with thermal comfort by having the opportunity to adjust or control the air condition of the building they occupy.

To better understand the HVAC system, let us take a look at the different types so you can decide as to why type of hvac equipment Australia you want to use in your home or office.

Single and Multi-stage 

A single-stage HVAC system is most popular in places with winter climates and humid areas. The system is set to provide comfort during the coldest or warmest time of the year. Most of the time, the system will operate at its full capacity even if you don’t want them to be. This is where multi-stage comes in. You can control how the system will operate thus helping you save money on energy consumption.

Zoned HVAC system

This is a single HVAC system that serves multiple zones or rooms. If you have a two-storey house or building, you can set the best temperature for each area so people will no longer argue as to what temperature is to be set on your thermostat. You have the option to make your upper building hotter or cooler than the lower building. Basically, a zoned HVAC system is a system where you can divide your home or office areas into different temperature. Its own thermostat of each room controls the temperature so no need to argue about the perfect thermostat setting.

Packaged HVAC system

This is a system where all major components are installed in one large cabinet. This type of HVAC system is commonly used in homes of offices without basements. This is usually placed outdoors. This system uses a blower to bring the treated air into the building and draw away the untreated air. The good thing about this system is that it doesn’t create too much noise since the system is installed outside. But then since it is located outdoors, they are prone to tear and wear quickly compared to other HVAC systems.

Ductless Split system

As per the name itself, the system does not need for ducting to be installed. Multiple units instead are used and placed in where the property owner wishes to have control over the temperature. These units are installed on the walls and then connected to the compressor outside the building. If you do not have ducting in your property, then this type of system would be the best option. A single unit is capable of providing treated air up to four units inside the property. Each unit has its own thermostat, so you are free to control the temperature setting for each room in your property. 

Geothermal HVAC system

This type of HVAC system uses the heat underneath the ground. It uses a heat pump powered by electronics to process fluid through the use of underground pipes to exchange heat. This system can also be used to cool down your properties. In this process, the heat that is collected from your property is released into the ground, and then it is absorbed into the cooler section of the earth. Then the extracted cool air is cycled back into the building. This type of system is proven to be environmentally friendly, energy-efficient and can help you save money in your utility bills. Although the installation of this type of system is expensive, you’ll eventually get your investment through your energy savings within 8 to 10 years.

Aside from the mentioned types, there are also other different types of an HVAC system. All of the systems have their own pros and cons. Understanding its functionalities and its limitations are important to help you decide on which HVAC system to get for your home or your office. Choosing the right HVAC system that fits your budget and suit your needs will result in a more comfortable lifestyle.

Important note

No matter what type of system you choose, make sure to hire a professional to install the HVAC system in your property. This is to ensure that the system is properly installed and work properly. Also, it is important that your HVAC system undergoes regular maintenance to ensure that it will work properly efficiently and can serve you for long periods.

Why Underground Parking Areas Are Hot

You might assume that underground parking lots would be fresh. Unfortunately, that is not the case. There are plenty of reasons for this. Below, we will be going over some of the different reasons why underground parking areas get so hot.

Reasons Underground Parking Areas Are So Hot:

  • Vehicles.

One of the reasons parking lots underground are so hot has to do with what is being stored in them. The fact is, a parking lot meant for vehicles. Because the majority of these vehicles are warm themselves, they give off a lot of heat. Therefore, it can cause warm air to take up the garage.

  • Exhaust Fans.

Another reason it gets so hot in the parking lots that can be found underground have to do with the exhaust fans that are needed throughout the garage. Because CO2 permeates throughout these garages due to the exhaust fumes, the garages require a lot of high-intensity exhaust fans which can give off a lot of hot air.

  • Driving Vehicles.

Another reason has to do with the fact that a lot of vehicles are actively driving throughout the day in these garages. Because of this, you are going to have constant exhaust fumes and hot cars, causing the air to heat up. This makes the entire garage feel much warmer as a direct result. The longer for the vehicles to park or exit because of a lack of parking guidance solutions, the hotter the parking area becomes.

  • Doors/Windows.

Garages typically do not have a lot of places for heat to escape. Because of this, the parking garage can heat up and cause the hot air to get trapped itself. This can cause the garage to feel much warmer than it should be.

Now that we have gone over some of the reasons parking garages can get so hot, we will go over some of the ways to cool it down.

  • Concrete.

Concrete is known to retain a lot of heat and allow heat to enter. Because of this, a hot day can cause the garage to heat up, and because garages cannot get rid of hot air quickly, it ends up increasing the overall temperature.

Ways To Cool Parking Garages Down:

  • Fans.

One of the ways you can cool these garages down is by investing in fans. By running fans at night, you should be able to get more air moving throughout the day. This will allow the garage to expel hot air much quicker, and it can help with overall circulation, which should make for a much more comfortable ambient temperature.

  • Open Air.

Another significant way to help cool down a garage that is located underground is by making it open-air parking. You can do this by allowing air to have plenty of room to escape. Because hot air rises, you could have portions of the garage opened to allow for the heat to escape easily.

Overall, there are plenty of different reasons these garages get so hot. There are specific ways you can cool them down, but underground parking is likely always to be reasonably hot.

To be a professional electrician.

What are the steps that differentiate a professional from the electricity of a person without training in this field? What points must be reinforced to be able to say that one is a good electrician?

  1. Use technical terms when speaking. So, for example, we will not say the blue wire, but the neutral. We will not call all switch mechanisms. We will not say gadget, but Magnetothermic or PIA, etc., etc.
  2. Handle tools with ease and agility. It is necessary to practice, peeling cables, splicing, screwing, etc., etc., to get some skill when doing the work.
  3. Use of the Tester or multimeter, quickly and concepts. We will measure, tensions, Intensity, Resistances, Continuity, Isolation, etc.
  4. Repair of faults in machines or electrical panels. Know how to read electrical diagrams and follow the circuits, replacing defective elements.
  5. Installation. Given a maneuver of a machine know how to design the electrical panel.

If you master these 5 points congratulations, you are a professional. If you lack one or all do not get discouraged with effort soon, you will get it.
